Phenotypic Stability Analysis for Seed Yield and its Associated Traits In advanced lines of Indian Mustard (Brassica juncea L. Czern and Coss)” was carried out to study the effects of different environments on seed yield and its associated traits, to estimate the magnitude of Genotype x Environment interaction and to find out the most stable and high yielding genotype among the selected lines of Indian mustard under different environments of different topography, soil texture and prevailing climatic conditions of Manipur. Fifteen genotypes were evaluated in 3 different locations (Andro, Iroisemba and Senapati) in RBD with 3 replications over two seasons viz; Rabi 2018-19 and 2019-20. The environment wise ANOVA revealed highly significant differences among all the genotypes studied for all the 11 characters of seed yield and its associated traits. The pooled ANOVA also indicated significant differences among the environments, genotypes as well as genotype by environment (GXE) interaction for all the traits. Genotype X Location interaction was observed as the main component for GXE interaction. Genotypes performed better in 2019-20 rabi season as compared to rabi 2018-19. Environment (E-5) i.e. Iroisemba, valley area was the best for expression of most of the characters studied. Stability Analysis using Eberhart and Russell indicated the significance of GXE (linear) for no. of siliqua/plant, no. of seeds/siliqua, siliqua length, no. of primary branches, no. of secondary branches, days to first flowering, days to 50% flowering, days to 80% maturity and 1000 seed weight except for plant height and seed yield per plot which shows the substantial amount of predictable G X E interaction for the expression of these characters in the selected genotypes. All the 15 genotypes were tested for 3 stability parameters, viz mean, bi and S2 di. The genotypes CAURMM-3, CAURMM-4, CAURM- 5, CAURM-4, PM- 25, CAURMM-1 and JM-1 were identified to be the high yielding and stable, hence they can be recommended for general cultivation under varied environments of Manipur. CAURM-1 CAURM-2, CAURM-3 had more stable characters although their yield was below the population mean, Therefore, proposed as promising genotypes for general cultivation under intensive input supply as they performed best in favourable environments, while NRCHB 101 found to be suitable for cultivation under poor environments.

Background and Objective: Brown sarson is gaining wide acceptance because of its adaptability for both rainfed as well as irrigated areas and suitability for sole as well as mixed cropping. Being a major rabi (winter season) oilseed crop, it has greater potential to increase the availability of edible oil from domestic production. In this background, the present investigation was carried out to generate information on the adaptive potential and stability parameters of ten diverse genotypes of brown sarson for varietal selection and stability in their performance to characterize the nature of genotype' environment for various yield and yield-related traits at various locations. Materials and Methods: The basic material for the study comprised 10 genotypes of brown sarson (Brassica rapa L.) grown in a 3-row experimental plot of 3 m length with inter and intra row spacing of 30 and 10 cm, respectively. The qualitative data generated through participatory rural appraisal (PRA) was analyzed by using a χ 2 -test. The data generated from replicated grandmother trials were analyzed through ANOVA. Results: Analysis revealed that all genotypes possessed significant differences in oil content. Mean squares due to GXE interaction were significant for the trait. The component analysis of the environment (GXE) revealed significant mean squares for the trait. Mean squares of linear and non-linear components revealed that environments (linear) were significant for oil content and the significant mean squares for E+(GXE) for the trait arose due to environments (linear) and linear response of the regression of the cultivars to the environment. Conclusion: Genotypes possessed significant variability for oil quality and oil content and could be used as parental stocks for crop improvement programmes.

The present study investigates the genetic variability and stability of 15 mustard (Brassica juncea) genotypes across four diverse locations in Jharkhand, employing a randomized block design with three replications. Significant differences among the genotypes are observed, with environmental factors and their interactions exerting a considerable influence. Utilizing the AMMI and GGE biplot methods, the study delves into the intricate interactions affecting economically vital traits such as seed yield per plant and oil percentage. The combined effect of environment and interaction explains a substantial portion of the observed variation of 79.6 and 58.9% on seed yield per plant and oil % respectively. The first two principal components together explained larger portion of 85.2% and 89.5% of the GXE variation of seed yield per plant and oil % respectively. The AMMI analysis had identified that, the genotypes Kranthi, PA-5232 and BAUM-09-12-1 for seed yield per plant and BAUM-08-18, Shivani, DRMRCI-70 and Pusa Bold for oil % are stable performers. The GGE biplot analysis and AMMI have commonly identified BAUM-09-12-1 and Pusa Bold as high yielding and most stable for seed yield per plant and oil % respectively. The results of AMMI identified ranchi as most ideal environment for selection of genotypes for both seed yield per plant and oil%, but GGE differs in-terms with Ranchi as ideal only for oil% and dumka for seed yield per plant. The availability of the above information of genetic variability and stability of genotypes for seed yield per plant and oil % can aid improving mustard production levels and self-sufficiency in edible oils.
